Bastl Instruments Quattro Figaro Manuel utilisateur
Quatro Figaro is a 4 channel VCA. Channels A, B, C,D are
organized in columns. Each channel has a gain knob with
a maximum gain of a little over 2.
Each CV input has an attenuator. The gain of the vca is
linear to the control voltage on each channel. The final
control voltage is the GAIN voltage + the attenuated CV
IN voltage.
Internal routing
Internal routing enables you to use the QF as a simple
and powerful panning tool. Two input pairs (A+B and
C+D) are internally routed via the jack switches, which
enables you to quickly setup a panning situation.
Because the internal routing is via the connector
switches, you can use all the channels independently by
plugging in cables which disconnect the internal routing.
Also the INVERTED CV OUT of channel A is connected to
the switch at the CV IN of channel B (the same with C
and D), which means that the inverted CV is connected
to the CV input of signal B as long as there is no jack
plugged into the signal jack of channel B.
For each CV there is an inverted output (not affected by
the attenuator).
the signal from channel A is routed to the switch at the
signal jack of channel B (the same with C and D), which
means that the signal from channel A is connected to
channel B as long as there is no jack plugged into the
signal jack of channel B.

QUAD VCA CV INVERTOR & MIX OUTS
Signal input goes thru the the VCA and is outputed to
signal out with gain linear to the CV.
Mixed outputs
The mixed outputs enable you to use QF as a voltage
controlled mixer or voltage controlled stereo panning
mixer. There are outputs of signal A mixed with signal
C, signal B mixed with signal D (note that these two
outputs are inverted), A+B+C+D mixed together and its
inverted version

Before connectin the ribbon cable to this module
disconnect our sstem from ower !
Double check the olarit of the ribbon cable and
that it is not shifted in an direction. the red cable
should match the -12V rail both on the module and
on the bus board !
lease make sure of the followin
you have a standard pinout eurorack bus board
you have +12V and -12V rails on that bus board
the power rails are not overloaded by current
Although we put protection circuits in the device,
we do not take any responsibility for damages
caused by wrong power supply connection.
After you connected everything, double-checked
it and closed your system, so no power lines can
be touched by hand, turn on your system and test
the module.
